Specification of Letters Patent.

Patented Apr. 2, 1912.

To all whom it may concern:

Be it known that I, JULIUS DORNETH, a subject of the German Emperor, and residing at Berlin, Germany, have invented certain new and useful Improvements in or Relating to Typograph-Machines, of which the following is a specification. I

My invention relates to improvements in the class of linotype machines known as the typograph, and .more particularly to im provements in the apparatus for distributing the matrices, and generally stated my invention is an improvement on the apparatus described and shown in my copending ap plication for typograph machines, Serial Number 423,954, filed March 2, 1909.

When the line is cast the pump dashes lead into the matrices under a high pressure. During this operation small drops of lead sometimes are spattered about the line holding means, and these lead spatters, as they are called, sometimes interfere with the operation of returning the matrices to their positions in the magazine. This results in the breaking of the matrix bars, or other damage to the machine.

The object of the improvements is, in case of these lead spatters, to prevent the distributing mechanism from being thrown into operation,whereby thematrices or other parts of the machine would be injured. For thispurpose my apparatus is constructed in such a way, that the matrix carrier is under the influence of a constantly operative force which tends to slightly rock the same, while it is normally prevented from being rocked by a suitable locking device. The distributing mechanism can not come into operation, unless the matrix carrier has been unlocked and slightly rocked by the constantly acting force. I

For the purpose of explaining the invention several examples embodying the same have been shown in the accompanying drawings in which the same letters of reference have been used in all the views to indicate corresponding parts.

In said drawingsFigure 1, is a side view of the machine seen from the right in Fig. 2, Fig. 1 is a detail side elevation of the switch block, Fig. 2, is a frontview ofthemachine, partly insection, and seen from the right in Fig. 1, Fig. 3, is an enlarged view of a detail, Figs. 4, 5 and 6, are sections of the detail shown in Fig. 3 taken on the lines II-II, IIIIII, and IVIV-respectively, Fig. 7 is a side view of a modified form of the machine seen from the left, Fig. 8, is a side view of Fig. 7 seen from the left, and Figs. 9 and 10, are respectively a front view and a side view of a further modification of the invention. i Referring particularly to the exampl illustrated in Figs. 1 to 6 of the drawings, the frame or matrix carrier A is mounted on a supporting or main frame B, whereon it is automatically tilted at intervals, as is usual in machines of this class. To the front side of the machine a rod 1 is secured which is adapted to be engaged by a hooked lever 2. The latter has its fulcrum on the 1 matrix carrier A at 3, and at its end opposite the hooked portion it carries a key 4. Through a slit 2 of the lever 2 there projects a pin 2 secured to a bracket'2 mounted on the vmatrix carrier A. By

means of the slit 2 and the relatively stationary pin2 the extent of the. movement of the lever 2 when depressing the key 4 is limited. A spring 5 secured with one end to the matrix carrier A and with its opposite end to the lever 2 has the tendency to hold the latter with its hooked end in engagement with the rod 1. When the hooked port-ion of the lever 2 is thus in engagement with the rod 1, the matrix carrier A can not be rocked. By depressing the key 4 the lever 2 is disengaged from the rod 1, so that the matrix carrier can be rocked. A spring 6 is secured with one end to the main frame B and with the opposite end to an arm 7 secured to the matrix carrier, and the said spring has the tendency to rock the carrier A out of its normal position shown in Fig. 1. When the lever 2 has been thrown out of engagement with the rod 1, the spring 6 rocks the matrix carrier A slightly upward. "In the operation of the machine the lever 2 and rod 1 are automatically thrown out of operation, after a line of type has been cast, and in the example shown this is done by means of the slightly held downward by the hand of the operator, so that the spring 6 cannot come into action, and rocking of the matrix carrier is prevented. As soon as the matrix carrier has been slightly rocked by the spring 6 the matrix distributing apparatus comes into action. For this purpose an arm 10 projecting from the matrix carrier is connected by a link 11 to a slide bar 12 which at its lower end carries a roller 13 and two laterally projecting pins 14, as is shown in detail in Figs. 4 to 6. The said pins slide within vertical guide ways 20 which are formed in blocks 18 and 19 disposed adjacent to a constantly rotating disk 15 which, in the example illustrated, is the main driving disk of the machine. On its face the said disk is formed with a spiral cam groove 16, as is shown in Fig. 2. After the carrier A has been slightly lifted by the spring 6, and moved the slide bar 12 downward, the roller 13 is engaged by the outer end of the cam groove 16. Therefore upon the further rotation of the disk 15 the slide bar is pulled downward, and the matrix carrier A is tilted, until the roller 13 is again disengaged from the cam groove 16 at the inner end thereof, and the carrier is released. To the carrier a weighted lever. 17 is secured which by the rocking movement of the carrier is rocked out of its vertical position, so that it rocks the carrier backward into its normal position, in which it is again locked by the hooked lever 2 engaging the rod 1. At their lower ends the guide ways 20 merge into branches 21 disposed at right angles thereto, and from which guide ways 22 extend vertically downward. Vhen by lifting the matrix carrier A the slide bar 12 is shifted clownward the pins 14 slide within their guide ways 20 downward, until they are engaged within the branches 21. Now the slide bar 12 is forced forward and into the position shown in dotted lines in Fig. 3 by a spring 23 actuating pin 23. Thereby the roller 13 is forced into the cam groove 16 which carries the roller and the slide bar con nected therewith downward, while the pins 14 slide within the portion 22 of the guide way. At the lower end of the guide ways 22 switch arms 24 are provided, and springs 25 normally hold the arms in a position in which the guide ways 22 are closed. By the pins 14 the said switch levers are pressed backward against the pressure of the springs 25, until the slide bar 12 arrives in its lowermost position. At this moment the rollers 13 are disengaged from the cam groove 16, and the springs 25 and switch levers 24 force the slide bar 12 and the roller carried thereby backward into their normal positions in which the pins can pass through the guide ways 26 and into the portions 205 In order to prevent the pins 14 from directly passing from the guide ways 20 into the guide. ways 26 when the slide bar 12 is moving downward, a switch mechanism is provided as follows: The upper part of the partition wall 27 provided between the guide ways 22 and 26 on each side of the slide bar 12 is formed by a rocker 28 which is normally pressed into the position shown in Fig. 3 by a spring 29 and which at its upper end provides the lower wall of the branch 21 of the guide way. These rockers prevent the pins 14 from passing from the guide ways 20 into the guide ways 26, while they permit the same to pass from the guide ways 26 into the guide ways 20. In order that the roller 13 may securely pass into the cam grooves 16 of the disk 15 the wall of the said cam groove is formed at its inlet end of a rocker 30 which is yieldingly pressed into the position shown in Fig. 2 by a spring 31. The rocking movements of the said rocker are limited by two pins 301 and 302.

In the example shown in Figs. 7 to 10 the matrix carrier and its rocking mechanism are so constructed, that the distribution of the matrices can not be effected, before the matrix carrier has been released by its locking mechanism provided by the lever 2 and the rod 1. For this purpose the mechanism for rocking the carrier out of its normal position is normally disconnected from the said carrier, and it is connected therewith by means of a clutch. This construction is better than the one described with reference to Figs. 1 to 6, because in the said example there resides some difliculty in inserting the roller into the cam groove 16 and removing the same from the said cam groove. The clutch is located on the shaft 15 which carries the main driving disk 15, and it consists of two clutch members 32 and 33, the member 32 being rigidly secured to the said disk and the member 33 being shiftable on the shaft 15 by means of a lever 35 fulcrumed at 34. At its upper end the said lever is formed with an enlarged portion formed with a groove 36. On a shaft 37 secured to the matrix carrier A an arm 38 is mounted which carries a spring actuated pin 39. Vhen the lever 2 is disengaged from the rod 1, and the carrier A is slightly rocked upward by the spring 6 the spring actuated pin 39 is forced into the groove 36 at the upper end thereof, and upon the further movement of the carrier it rocks the clutch lever 35, until the clutch members 32 and 33 are in engagement with each other, whereupon the pin 39 leaves the groove 36 at the lower end of the same. The clutch member 33 is connected with a sprocket wheel 40, and if the clutch members are in their coupling position the said chain wheel is rotated by the disk 15. By/

such rotation of the sprocket wheel a chain 4,

which is guided on the latter and on a.pul' ley 41 is wound up. At one end the said chain is secured to the arm 42 and at the opposite end to a tension spring 43. The

rocking movement of .the matrix carrier impact, and it puts the spring 6 under tension which now acts as a brake. When the carrier has come to a stand still, it is immediately pulled backward by the tension of the spring 6, which spring again acts as a brake near the end of the rocking movement of the matrix carrier. It is manifest that when the main frame A swings downwardly to its setting position the arm 7 extends the spring 6, and that, therefore, the said spring while under tension will serve as a brake to gradually stop the downward swinging movement of the frame A. This spring is so proportioned and tensioned that it brings the carrier to rest with the smallest amount of jar possible. When the matrix carrier is thrown to its upper or distributing position the arm 7 swings across the line between the center of the matrix carrier shaft and the lower pivotal connection of the spring '6. After the said arm passes said line it extends the spring 6 and then the tension of said spring serves to retard the movement of the carrier and the spring is then acting as a brake. The momentum of the. matrix carrier and the weight 17 is suflicient. to move the carrier to its distributing position, but as soon as its movement is arrested the spring 6 will be under sufficient tension to return the carrier to its normal setting position. The weight of the carrier and of the weight 17 will be sufiicient to extend the spring 6 upon the return movement of the carrier to its setting position, and the latch lever 2 will engage the bar 1 and thereby hold the spring 6 under considerable tension, so that when said latch lever is released the spring 6 will start the carrier on its upward movement and move it sufliciently to bring the roller 13 into the path of the pivoted rocker 30 of the cam groove 16. To prevent the lever 42 from striking on the driving disk 15 when the matrix carrier A is rocked it is jointed to the lever 38 at 47 so that it can rock upward independently of the lever 38. The

clutch lever 35 carries a pin 48 which provides a support for the lever 42 before the latter comes in contact with the driving disk 15. Instead of the connecting means a part of which is formed by the chain other means may obviously be provided.

In the example shown in Figs. 9 and 10 the mechanism for throwing the clutch members 32 and 33 into cooperation is the same as that described with reference to Figs. 7 and 8. .However, the clutch member 33 is not connected with a sprocket wheel, butwith a spur gear 49 which is in mesh with a spur gear 55 of larger diameter. To the latter a driving wheel 50 is secured which is in engagement with a toothed rack 51 connected with the matrix carrier through a link 52. By throwing the clutch member 33 into operative position the matrix carrier is rocked through the intermediary of the toothed rack 51 during the downward stroke thereof. The clutch is thrown out of operation by means of the lug 45, engaging the upper end of the lever 35 and disconnecting the members 32 and 33 of the clutch, whereupon the carrier com; pletes its movement independently of its ,driving mechanism, and it is rocked backward into its initial position in the manner described with reference to Figs. 7 and 8.
